+## Sample: IntroParamsAllValues
+
+If you want to use all possible values of an `enum` or another type with a small number of values, you can use the [`[ParamsAllValues]`](xref:BenchmarkDotNet.Attributes.ParamsAllValuesAttribute) attribute, instead of listing all the values by hand. The types supported by the attribute are:
+
+* `bool`
+* any `enum` that is not marked with `[Flags]`
+* `Nullable<T>`, where `T` is a supported type
